What you see below the table are clues. A clue tells you how to arrange a pair of items in the table relative to each other. A clue with a left-facing arrow tells you that the first item will be placed directly to the left of the second item in the table. A clue with an equal sign tells you that its items can only be in one column of the table. But don't worry, the game itself gives you these clues to the correct order. You just need to find a place for each item.
